Management refuses to even speak to clients

As a customer who is forced to deal with Pharmacy direct by my medical aid Bonitas I am very disappointed in the lack of service and commitment.<br> My requests are never adhered to and any request to speak to a manager is denied, I even visited the offices and heard the manager tell the receptionist that he/she has no time to speak to clients? <br> I am battling to manage my diabetes as result insulin shortage due to non-delivery by pharmacy direct<br> I am confused why I am forced to deal with a supplier that has no interest in my wellbeing or health or even speak to me? <br>
